Amoxicillin dosage and length of treatment for cat?

  • (I run a small cat sanctuary and am currently between vets. I'm trying to learn to do some basic treating on my own. I know when a cat is sick enough to call a vet so please don't just tell me to go to a vet. That doesn't answer my question.)

    I've been doing urinalyses on my herd and am finding urinary issues from not drinking enough and probably from an all dry diet. Some cystitis and some infection. I've found a good natural compound that treats the cystitis really well, but not the infection. So I've started them on amoxicillin for UTI, I'm just not sure the correct dosage and length of treatment for each cat. When I've looked elsewhere online, I've seen 5-10mg per pound and 10-25mg per pound. Also, nothing really says for how long to give it.

    Can someone offer me some better specifics on this? I've been treating conservatively so far (10mg per pound) and only for about a week but I'm still getting leukocytes showing up when I test them. I know people usually have to take a 2 week course to treat everything, but I wasn't sure about animals. Honestly, it's been so long since I've used anything but the Convenia shot, I can't remember. I'm trying to treat the infection without overwhelming their system as I just had two cats die after having the Convenia shot.

    Looking for some better guidelines here. If you think it might require further testing, I'm completely open to that. Thanks.

    I'm voting to close this question as off-topic because this is asking for expert veterinarian advice. This site does not replace a veterinarian consultation.

At least a consultation with a vet would clear this up for you and give you the answer and whether the treatment is warranted.

    Thank you all for your replies. Since I posted this, I have found a great new vet that works with me and helps me learn. To check urine I do the stick, check urine gravity with a refractometer, and am learning to use the microscope to find white blood cells. The urine gravity has been the best indicator of an issue so far. The cats do better in the winter, so I've been able to take a break for a few months, but summer is coming soon. I'm finding ways to get more water into their diet and I've gotten down the dosing on the antibiotics (which I'm trying to use less of because they disrupt their

    I know that most people don't recommend home treatment without a vet consultation, but the reason for that is not only the dosage amount, but the type of antibiotics given depend on the type of infection. Not to mention the fact it is tedious to get antibiotics without a prescription. But it is hard to justify a pricey vet bill when you already have what will be prescribed.

    My cat came home a few times with a paw infection, and I gave him some of my own antibiotics-amoxicillin, the complete treatment took about 1 or 2 500 mg pills. The dosage is 5-10 mg per lb., and like humans, the first dose or two should be the maximum (10 mg per lb.) and then reduced to the minimum. This is to kill the majority of the infection and not lead to antibiotic resistance and then once that is accomplished the intent is not to strain the system by ingesting unnecessary amounts, but to maintain the resistance to the infection until it is gone.

    Once the dose is reduced to the minimum it should be maintained until the cat is healthy again and a few days after just to make sure the infection has been eliminated. It is better to make sure it is gone that to resume treatment after an infection re-establishes. I administer half the dosage of 5 mg per lb twice a day (5 mg X 10 lbs= 50 mg per day; twice a day that means two doses of 25 mg) to make sure it is always in the system, just as recommended for humans, morning and evening doses. I wait for a few days or a week after the symptoms have disappeared, just like I would for myself. The whole treatment is usually two weeks or so. The most important thing is to wait until the cat seems healthy again and then keep giving the minimum dosage for a short time after that just to make sure.

    welcome to the site. This is a good answer. I am concerned whether this question is a good fit for the site. Discussing medication dosing for pets, that should be prescribed by a vet. Please continue to contribute. :)

    I know this answer has been accepted, but it is terrible medical advice. DO NOT GIVE HUMAN ANTIBIOTICS TO CATS in this way, and DO NOT TAPER them as described. This reflects a very poor understanding of antibiotic pharmacodynamics, which is exactly why vets are trained to know when and how to prescribe these medications.
